* autoconf.m4: Instead of reactivating the macros before reading

Autoconf's file, do it afterwards, so that Autoconf promotes the
right use, but users still can use the old names.
Of course this revealed numerous non updated uses of old macros in
Autoconf's files.  Adjust them.
But for the time being, keep `define' alive for Autoconf.
